It’s not just 2023 though. Didn’t Nino years like 1976(or was it 1977) and 2002 do the same? I know 2002 had April heat and a very cool May. Obviously those years didn’t end up being strong Nino. I think it’s more of just a “Nino thing” regardless of eventual strength.

Yes, we have had numerous 90°+ events in the Northeast during developing El Niños in April. But the 500mb forecast most closely matches 2023 with a shift to strong blocking. Makes sense since this one is coupling with the atmosphere and is much stronger early on like 2023.

Can really see how things start to diverge in terms of position of the warmest SSTa’s after December. With Nino 1+2 warmth (east-based), Jan and Feb are also warm. With Nino 3.4, the correlation starts to break in Feb. With Nino 4 (central to west pacific), it actually correlated to a cold Feb. So while December is universally expected to be mild regardless, whether we get a backloaded winter or near wall to wall torch is based on whether the anomalies are focused on the Eastern Pacific vs Central.

 Based on the above maps for Jan, I’m going to consider renting a place in Anniston, AL, just for that month.

I see the SOI has gone strongly positive in the last couple of days. I don’t know how long that’ll last though.
